Games will be three innings each and the regular season is scheduled to go through April 28.

The top eight players will reach the postseason, which culminates in a May 2 World Series. A best-of-three format will be applied to the playoffs until the World Series, when best-of-five is used.

Sony Interactive Entertainment and Major League Baseball, in cooperation with the players association, will donate $5,000 on behalf of each player to a Boys and Girls Club in their community. A total of $175,000 will be donated, including the World Series prize of $25,000.

The majority of participants are under the age of 25, but a few grizzled veterans -- 34-year-old Matt Carpenter of the St. Louis Cardinals and 34-year-old Carlos Santana (Cleveland Indians) -- are also in the competition.
